A friend of mine got PTSD from piloting huge nuclear subs in subsea ravines with a clearing of only one inch on each side of the sub. One wrong move, and the entire crew is gone. He also had to do this in conditions similar to surface storms. Looks like autonomous or automatic systems may be developed for those kinds of manoeuvres now, if it is truly that precise. Seems like a huge leap in navigational systems.
- HyperSane 3y agoThere is no way that subs can be controlled accurately enough to do that.
- bottom999mottob 3y agoThere is no way anyone would hyperbolize the experience of their friend squeezing a submarine through ravines on the internet.
- UberFly 3y agoSqueezing submarines through internet ravines sounds really interesting. Go on.
- reportgunner 3y agoIs there a library for this ?
- yodon 3y agoWhen a storyteller has clearly hyperbolized the parts of their story that can be fact checked, they have destroyed any reason to believe the remainder of their words.
- verisimi 3y agoAn inch! He was lucky! My friend was only given half an inch, and that was considered generous!
- marginalia_nu 3y agoYeah, of course we had to row the damn thing too. Uphill and sub-freezing temperatures, both ways.

- andromeduck 3y agoA few meters of clearance I could beleive but I don't think the hydrodnymaics and control/reaction times works allows for that at all even if you had the measurements nailed.
- kortilla 3y ago> One wrong move, and the entire crew is gone. Not really. Subs don’t move that fast in those tight of conditions. One wrong move and the sub bumps the canyon wall making a bunch of noise. Unless they are in actively hostile waters, it just means loss of stealth and the sub needs to choose a new location to lurk.
- LgWoodenBadger 3y agoOh come on... "On 8 January 2005 at 02:43 GMT, San Francisco collided with an undersea mountain about 364 nautical miles (675 km) southeast of Guam while operating at flank (maximum) speed at a depth of 525 feet (160 m)." https://en.wikipedia.org/wiki/USS_San_Francisco_(SSN-711) https://en.wikipedia.org/wiki/USS_San_Francisco_(SSN-711)
- kebman 3y agoSo, here's an anecdote of a sub that miraculously survived a head on collision. What's your point? From the same article: “The collision was so serious that the vessel was almost lost; accounts detail a desperate struggle for positive buoyancy to surface after the forward ballast tanks were ruptured.” I doubt these are problems any submarine crew wants to deal with, even at slow speeds. Besides, one sharp edge at the sides will open her right up like a tin can.
- pnpnp 3y agoI can't speak for the poster, but I would guess it's something along the lines of "military subs are pretty tough," and the bit about killing everyone onboard with a slow collision may have been an exaggeration. They are meant for warfare and surviving torpedo concussions as much as possible, so depending on speed, a slow scrape with terrain might not be fatal.
- kebman 3y agoOr it might be fatal. You don't know that. What we do know is the general construction of a sub, which is that of an "egg". It's built to withstand extreme global pressure (pressure from all sides at once, like water does). But as I'm sure you've noticed, eggs don't hold up very well against needles.

- dekhn 3y agoI think your friend may have embellished both the accuracy and the risk (not to say that piloting a sub is completely stress free, obviously).
- pnpnp 3y agoAlso maybe not! I don't know what the phenomenon is called, but large ships going though the canals create their own buffer to some extent. It's pretty cool!
